Artificial intelligence (AI) is the simulation of human intelligence processes by machines, especially computer systems.
The term AI is often used as an umbrella term for machines that are capable of perception, logic, reasoning, and learning.
Another useful way to think about AI is in terms of a spectrum from automation (rules-based) to intelligence (learning systems) applied to various problems or use cases.
Machines are good at repeating processes and producing predictable outcomes.
What machine learning provides is the identification of patterns and anomalies; and then scaling, repeating and producing consistent results.
AI enables optimisation and intelligent automation to augment human ability. Systems can now be built that perform functions way beyond the limits of current human ability.
